Performance class (capacity)

The capacity depends on your water hardness and water consumption. You can determine the capacity using our capacity calculator or this rule of thumb:

Water hardness rule of thumb
Medium-hard water (8–14 °dH) Number of people x 7.5
Hard water (14–21 °dH) Number of people x 10
Very hard water (over 21 °dH) Number of people x 12.5

Example (4 people with a water hardness of 20): 4 x 10 = 40
